IMPROVEMENT IN DUMPlNG-WAGONS.

Specification forming part of Letters Patent No. 39,478, dated August11, 1863.

To all whom it may concern.-

Be it known that I, R. W. GREEN, ofBradford, in the county of McKean andState of Pennsylvania, have invented a new and Improved Dumpin g-WVagon;and I do hereby declare the following to be a full and exact descriptionof the same, reference being bad to the accompanying drawings, makingpart of this specification, in which Figurelis a side elevation of myimproved device. Fig. 2 is a vertical transverse section of the same.

Similar letters of reference indicate corresponding parts in the twofigures.

The subject of this invention is a wagon or vehicle wherein dirt,gravel, sand, 850., may be conveyed, and from which the same may bequickly and readily discharged.

The invention consists, essentially, in the combination of apeculiarly-constructed dirtreceptacle, with chains working upon awindlass, to which rotation is imparted through the medium of suitablegearing, all as will be hereinafter explained.

To enable others skilled in the art to which my invention appertains tofully understand and use the same, I will proceed to describe itsconstruction and operation. B B in the accompanying drawings repres ntthe front and hinder pieces, respectively, of the framing of the wagon,and Q Q the side pieces. To the inner sides of the pieces Q Q areattached vertical bolsters A A, the purpose of which is to provide meansfor the attachment of cross-pieces or beams R B. To the under side ofthese beams itis designed to attach in any suitable manner the truck ofan ordinary farm-wagon. YVithin the framingthus formed is suspended orpivoted the dumper or receptacle for the gravel, sand, 8w. This dumperis formed in two curved or circular pieces, J J, the upper ends ofwhich, when the dumper is in its normal or closed position, will beflush with the tops of the side pieces, Q Q- Each division of the dumperis provided at its respective ends with a metallic frame, K K, upon theend of which is formed a pivot, L, journaled in a metallic box, P,rigidly fastened to the front and hinder pieces of the framing of thewagon in any suitable manner. The pieces J J have hinged or jointed totheir lower end a section or piece, M, which, when the dumper is inposition for the conveyance of a load, conconstitute a perfectly levelfloor, whereby the dumper is rendered lessliable to be forced open bythe pressure of its contents than were the curve of each of thedivisions J J extended to the lower terminus thereof.

G G are braces which serve to impart additional strength to the framingof the wagon.

n n represent metallic bands or braces secured to the outside of thepieces J J to impart strength thereto.

0 is the drivers seat, within which is journaled a transverse windlassor shaft, E. Upon and near each end of the shaft E, and within theinclosure O, a chain or rope, F, is securely fastened. At their oppositeends the chains F F are attached, respectively, near the lower edges ofthe divisions J J of the dumper. V

-D is a gear-wheel keyed on the outer end of the windlass E and workinginto a pinion, D, on a short shaft, which is journaled in the seat 0 androtated by means of a crank, H.

I is a step for the feet of the driver.

When in their closed position, the divisions J J may be thus retained bya transverse rod or bar, R, held in the desired position by a button, R.

The operation will be understood from the foregoing description.

The dumper may be opened to discharge its contents by turning the crankH in either direction.

Owing to the peculiar form and arrangement of the dumper and the devicesfor suspending or sustaining the same, very little power will berequired to turn the crank, and hence the dumping operation may beperformed with as great celerity as may be desirable.

The pieces J J may be so arranged as that the force of gravitation willbe sufficient to cause them to resume their closed position, or this maybe effected in any other desired way.

I am aware that it is common to construct dumping-wagons with movablebottoms, and also that the gearing D D and windlass and Y with circularsides J J and hinged sections M chains E F F are old devices, and 1 donot M,in combination with the pivoted frames K wish to be understood asclaiming either of K, all arranged and operating substantially as thesedevices, broadly; but, and for the purposes specified.

Having thus described my invention, What I I claim as new therein, anddesire to secure by R. W. GREEN. Letters Patent, is

The box or body of the dumper, constructed In presence of- A. K. JoHNsoN, S. WALKER.
